The issue I see in that video is that the "window" for the animation is not properly set, looks like it may be off by a pixel or two. I can't reproduce this on Windows, and I haven't heard of others seeing this on OSX so it's probably just limited to Fedora.

Do you have your DPI set to a non-integer value?

I do have a non-integer value (1.3) for the field `layout.css.devPixelsPerPx`, and the issue won't happen if I change it back to 1.
